Mohammad Samiul Islam c87781a020 Add a product flag that will enable compressed APEX on device 
The product flag is only defined in this CL. No device has been
configured to use this flag yet.

The flag is overridable using environment variable. This way, developers
can enable APEX compression on various targets.

Bug: 137802149
Test: build/soong/soong_ui.bash --dumpvar-mode PRODUCT_COMPRESSED_APEX #false
Test: export OVERRIDE_PRODUCT_COMPRESSED_APEX \
  build/soong/soong_ui.bash --dumpvar-mode PRODUCT_COMPRESSED_APEX #true

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
